Hi dear all,
ZOU-HE boundary is considered to be a good method for the boundary condition problem in 2D. When I try to use that, a problem confuse me for a long time.
The four corner node cans not apply the same method as other nodes on the boundary because the corner nodes have 5 unknown node population while other nodes on the boundary only have three unknowns. I just use the Central difference to make the corner nodes the same as others. But the result is not good enough.
Can somebody who knows how to solve this problem tell me how to do that or suggest some related paper?
Best wishes!
